When a person converts to Islam automatically all his previous sins have been forgiven. How can a person's sins be forgiven on the spot when he or she didn't ask for forgiveness?

Dear Brother / Sister,

It is a favor and grant from Allah. Allah is the owner of the all property and He can forgive all sins if He wishes.

All the sins of a new Muslim are forgiven, except the violation of the rights of others. The good deeds done by the new believer before are not wasted; all his other (previous) sins are forgiven at the moment he becomes a believer.
